Parametrics

The VI-200 Family, with over 8 million shipped, is Vicor''s first generation of "zero-current-switching" component-level DC-DC converters. Operating at frequencies to 2 MHz, VI-200 Family Converters offer exceptional power density, efficiency, noise performance, reliability and ease of use. Power Boosters provide a simple, cost effective, off-the-shelf solution for higher power output requirements. One or more boosters may be used to create synchronous arrays capable of supplying several kilowatts of output power. The flexibility of Vicor''s power components is also available in half-size, half-power VI-J00 MiniMods. (pg. 72)

Overtemperature shutdown 95°C typical (recycle power to restart).
For additional output power use "Boosters". Change (VI-2xx-xx) to (VI-Bxx-xx).
* Brownout 75% of rated load; transient voltage for 1 second.
